Photography With Lens Reversed; Mounting/Detaching Rs Ring And Lens; Slide Duplicating - Mamiya Auto Bellows M645 Instructions Manual

Photographing with Lens Reversed
For macrophotography with magnifications larger than life size,
mounting the lens reversed by the use of the Reverse Ring, an
optional accessory, provides better lens performance for more
image quality.
The Reverse Ring comes in two types - the RS-67 ring for the
67mmo filter size and the RS-58 ring for the 58mmo filter size of
lens.
Mounting R6 Ring and Lens
1. Fit the RS Ring on the Front Standard (6) by aligning the
Alignment Dot on the ring with the Alignment Dot (9) and turn
the ring clockwise until it stops. (Fig. 20)
2. Turn the Adjusting Ring (A) of the RS Ring counterclockwise
to loosen it a little.
3. Screw the lens into the RS Ring.
4. If the red dot at top center of the lens is not located exactly on
the top, turn the lens counterclockwise and loosen or fasten the
Adjusting Ring (A) to set the lens so that the red dot stops right
at the top. (Fig. 21 )
* It is also possible to screw the RS Ring into
the lens first and then attach the ring on the Front Standard of
the bellows. In this case, turn the Adjusting Ring (A) so that the
red dot at top center of the lens matches with the "Mamiya"
mark on the rear of the RS Ring.
5. When using an 80mm lens, fit the second notch of the scale
onto the Scale Attaching Screw (12). When using other lenses,
fit the first notch on the screw.
6. For metering, set the A.M. Lever of the lens at "M" (manual).
The Double Cable Release will not couple to the bellows when
the lens is mounted reversed.
7. For other operations, follow the procedure as if the lens was
normally mounted on the bellows.
Detaching RS Ring and Lens
1. Turn the lens counterclockwise and detach it from the RS
Ring.
2. While pushing the Lens Release Lever (7) of the Lens Board,
turn the RS Ring counterclockwise until it stops and detach it
from the Front Standard.
